- 'CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 281,094, dated July l0, 1883. n

Application filed April 10,1883. (No model.)

, lings in which the cars are coupled by means of links and pins passing through vertical -openings in the draw-heads; and the main object of my invention is to provide a cheap and simple attachment which can be readily applied to the couplings nowin actual use, more especially those of the freight-car pattern, to-

render the coupling of the cars automatic. This object lattain as moretfully described hereinafter.

In the accompanying drawings, Figure 1 is a view of a pair of draw-heads to which my improvements have been applied, one of the couplings being shown in section, with the couplingpin held in an elevated position, ready for coupling, while in the other the link is shown held in a horizontal position by the coupling-pin and my attachment. Fig. 2 is a perspective view, illustrating the manner of applying my attachment to a common form of coupler; and Fig. 3 is a transverse section on the line l 2, Fig. l. A

Although my invention may be applied to any of the various styles of draw-heads in common use, l have illustrated in the drawings only one form-the common wrought-iron freight-car draw-head, open at opposite sides. Through vertical openings near the front of the draw-head passes the usual coupling-pin.

My attachment, as illustrated detached in Fig. 2, consists of a plate, D, carrying a sliding block, E, acted on by a spring, F, and guided and held in position by two lugs, d d', the former preferably passing through a slot in the block E, while the lug d is perforated for the passage of the rounded shank of the block. The spring F shown in the drawings is a spiral spring 4coiled round the shank of the block E, and bearing at one end on the lug d and at the other on a shoulder on the block,

to push .the latter in the direction of the arrow, Fig. 2, as far as the lug d will allow; but arubber or other form of spring may be used for the same purpose.

This attachment is secured in the drawhead in such a position that -the outer end of the block E will project to about the center of the vertical openings for the coupling-pin, so as to sustain the pin in an elevated position, as shown at the left of Fig. l. A link, L, held in the draw-head of an approaching car, will strike the end of the block, force it inward against the action of the spring F, and allow the pin B to drop into position.

To secure the attachment in they coupling the latter need not be removed from the car or disturbed, as it will suffice to bore two holes, a a, Fig. 2, in the bottom of the drawhead and tap corresponding holes in the plate D, and the attachment can then be secured by screws b b.

I prefer to make the plate D of a length to iit closely in the drawhead between the front and rear plates of the latter, in which case an opening is made in the plate to correspond with the openings in the draw-head for the passage of the coupling-pin B.

l claim as my invention,-

l. The combination, with a draw-head, of the plate D, adapted to and detachable from the head,A and the spring-block E, carried by and guided on the said plate, substantially as set forth.

2. The combination of the drawhead of a coupling with a plate, D, having lugs d d, and a slotted block E, having a shank passing through one of the lugs, and a spring, F, substantially as set forth. In testimony whereof l have signed my name to this speciiication in the presence of two` subscribing witnesses.
